Invoices, delivery notes and contracts in many countries still need the company stamp next to the signature. Printing, stamping and scanning every document takes a while. With a photo of the stamp you do it once and reuse it.
1. Take the photo
Stamp a clean sheet of white paper and photograph it with your phone:
- Daylight or a bright lamp, no flash: flash leaves a glare spot.
- Hold the phone flat over the paper, so the round stamp stays round.
- Fill the frame with the stamp. More pixels mean sharper edges.
A shadow across the paper is fine. It’s removed with the paper.
2. Turn it into a transparent stamp
- Open the PDF and click Sign.
- Choose Photo, then Choose a photo, and pick the picture.
- The paper turns transparent, and so do its shadows and the grey of a phone photo. What’s left is the ink.
- If specks of paper remain, move Clean up the background further. If thin lines of the stamp start to fade, move it back.
- Leave the ink colour on As in the photo so a blue or violet stamp stays blue or violet. Black and Blue recolour it, which suits a signature better than a stamp.
3. Place it
Click Place signature, then click where the stamp goes. Drag it into position and pull a corner to resize it, so it matches the size of the real stamp. Stamps often overlap a signature a little, as they do on paper.
Download the PDF and the stamp is part of it.
Sign and stamp together
Add your signature the same way, drawn or from a photo, and place it next to the stamp. The editor remembers the last three you used, in your browser only, so next time both are one click away.
A word of care
A stamp on paper has legal weight because only you hold it. A picture of it can be copied by anyone who has the file or the photo. Keep the photo private, and don’t leave it on a shared computer.
That’s also why the photo is handled in your browser and never uploaded. Your stamp doesn’t end up on someone else’s server.
